Storage drum in turning devices of sheet-fed printing machines

Abstract

The invention relates to a storage drum in turning drives of sheet-printing machines. It is an object of the invention to change the relative angular position of sheet-holding positions at a storage drum in turning devices with little expense and simple means. Pursuant to the invention, this objective is accomplished owing to the fact that sheet-holding systems (8, 9) are provided at the storage drum for taking hold of the sheets (7) in the front and rear regions, the sheet-holding systems (8, 9) can be adjusted relative to one another in the circumferential direction, the sheet-holding systems (8) for the front region of the sheet at the basic body (12) and the sheet holding systems (9) for the rear region of the sheet is assigned to a central axis (13), which is taken up by the basic body (12) and the sheet-holding systems (8, 9) are connected to one another by a clutch (18, 20), which can be released by means of the oil of an oil-under-pressure connection (29, 30, 31, 32).
